While doing a little websurfing this morning I came across this list of players who are without options this season. For any of these players to return to the minor leagues, they must clear waivers first.
The List was compiled by MLBtraderumors.com, then blatantly stolen by me to post for all your enjoyment.
On a side note, if you don't know about MLBtraderumors.com i suggest you click the link. They do an amazing job of compiling all the MLB player news across the league.
